Hard Drive Earrings

Wearing my new earrings

The newest in my collection of geeky jewelry: glass hard drive platter earrings.

tiny platters

We picked up a tray of tiny glass platters at a local surplus shop some time ago, marked “Tear Down Qty: 25 pcs.”

CF card for comparison

These one inch platters were used in Microdrives, which were designed to fit into CompactFlash card slots. (Shown with CompactFlash card above for scale.) They were used in (among other things) the iPod mini. After 2006, CF cards outpaced the capacity of the fragile Microdrives, and they’re no longer manufactured.


The platters are attached to the earring hooks with magnet wire. They’re incredibly reflective, and everywhere I wear them, spots of light are dancing around me.

The Tenth Bay Area Maker Faire

10 years of Maker Faire Panel

The 10th Bay Area Maker Faire was absolutely awesome. We reconnected with old friends, made new ones, and talked a whole lot. Above, my panelists talking about the past ten years of Maker Faire. Below, Windell talking about his new book, The Annotated Build It Yourself Science Laboratory. We saw many amazing things, some of which we captured with our camera sensor and have posted in a flickr album here.

Book excerpt on Polarized Light Filters

The Make Blog is featuring some excerpts from The Annotated Build It Yourself Science Laboratory.

In modern times, our contemporary Maker and Maker education movements have helped to rekindle our cultural interest in hands-on education, especially in the STEM and STEAM fields, in a way that hasn’t been seen since the 1960s — which is why it’s such a good time to bring this book back.

Analog Education and the 555

The article Can Analog Circuits Inspire Budding Engineers? over at Planet Analog discusses preparing students for dealing with real world circuitry by getting them started with analog circuits.

By building, probing, and observing the signals and their changes in these circuits without any code requirements, students can get a real feel for otherwise abstract concepts such as voltage, current, and more.

The author uses examples of projects and kits including our very own Three Fives Kit.

MakerCon 2015

MakerCon is a short conference put on by Maker Media in the week leading up to Maker Faire about the business of making.

Gael with InMoov

3D printing is a common maker topic, and MakerCon brought a few different twists to it. Above is Gael demonstrating InMoov, an open source 3D printed humanoid robot. There was also an incredibly inspiring talk about applications for medical 3D printing by Dr. Glenn Green.

Gigabot print

3D printing can be whimsical as well, as demonstrated by this “25 mm” drill bit by Gigabot.


The folks from Strawbees had built a quadcopter rotor cage with a clever servo actuator for flapping sculptural wings.

Clever flex design

I enjoyed seeing this attractive laser cut living hinge at the BotFactory demo.

Rogue Rover

Rogue Rovers are electric semi-autonomous ATVs designed for agricultural use to reduce farm injuries and pollution.

More pictures from the event are in my flickr album.

I am extremely excited that I’ll be  at Maker Faire moderating the panel Looking Back at Maker Faire on Sunday, May 17 at 11 am on Center Stage.

My panelists include long-time Maker Faire stars:
